Installation to Solid Concrete and Cinder Block Wall
1Position wall plate (AA) on wall so that upper slots
are 2.1" above desired center of screen. Use wall
plate (AA), making sure that it is level, as a template
to mark holes. Drill four 5/16" (8 mm) dia. holes to a
minimum depth of 2-1/2" (64 mm). Concrete must be
2000 psi density minimum. Insert anchors (DD) in
holes flush with wall as shown in figure 1.4. Place
wall plate (AA) over anchors and secure with
#14 x 2-1/2" (6 mm x 64 mm) wood screws (CC) as
shown in figure 1.5. Make sure wall plate is level and
tighten all fasteners.
• When installing Peerless wall mounts on cinder block, verify that you have a minimum of 1-3/8" of actual concrete
thickness in the hole to be used for the concrete anchors. Do not drill into mortar joints! Be sure to mount in a solid
part of the block, generally 1" minimum from the side of the block. Cinder block must meet ASTM C-90 specifications.
It is suggested that a standard electric drill on slow setting is used to drill the hole instead of a hammer drill to avoid
breaking out the back of the hole when entering a void or cavity.
• Concrete must be 2000 psi density minimum. Lighter density concrete may not hold concrete anchor.
• Make sure that the supporting surface will safely support the combined load of the equipment and all attached hard-
ware and components.

• Tighten wood screws firmly, but do not overtighten.
Overtightening can damage the screws, greatly
reducing their holding power.
• Never tighten in excess of 80 in • lb (9 N.M.).
• Concrete anchors are not intended for attachment to
concrete wall covered with a layer of plaster, drywall,
or other finishing material as shown right. If mounting
to concrete wall covered with plaster/drywall is un-
avoidable, plaster/drywall (up to 5/8" thick) must be
counterbored as shown below. Be sure concrete
anchors do not pull away from concrete when tighten-
ing screws. If plaster/drywall is thicker than
5/8", custom fasteners must be supplied by installer.
